It's Halloween night 2004, and two young women are brutally stabbed to death in their Napa Valley home. Police gather plenty of forensic evidence, but have no suspects until the victims' surviving roommate consults L.A. mediums Marti and Michael Parry. Their visions about the murder and crime scene prove to be eerily accurate, and when they agree to help police with the investigation, they predict the killer is close to home. Can the psychics help the police track down a cold-blooded killer?
